Fast, Reliable Bathroom Remodeling Across Stanton
Bathroom remodeling in Stanton typically runs $14,000 – $28,000 for a full gut-and-replace on a 1950s tract hall bath, with shower pan and waterproofing work alone landing between $3,500 – $7,500. Most Stanton jobs take 2 – 4 weeks once we open walls and confirm what’s behind them. We work throughout the 90680 ZIP code every week, so we know what these homes hide. Call (833) 863-7015 to schedule a free estimate and we’ll walk the space with you before quoting anything.
Stanton is different from the larger-lot cities around it. Roughly 3.1 square miles of near-total buildout means there’s no room to push a bathroom outward. Every upgrade goes vertical or works inside the existing footprint. That changes how we plan, price, and permit every remodel we do here.
Why Guest House ADU Builders Is Stanton’s Preferred Bathroom Remodeling Company
We didn’t arrive at Stanton bathroom work by accident. Our Bathroom Remodeling team has worked enough 1950s tract homes in the 90680 core to know the hall baths here share a common DNA: shallow plumbing runs, original cast-iron drain legs, and panels that were sized for a different era. That experience means we quote realistically up front, not optimistically and then revise later. When a homeowner off Beach Blvd asks us why a neighbor’s quote moved mid-job, we can explain exactly what was likely found, because we’ve opened the same walls on the same block.
Stanton homeowners call us because they want one accountable team, not a patchwork of subs. We handle demolition, rough plumbing, electrical corrections, tile, waterproofing, and finish work under one roof. That matters on small lots where coordinating five trades gets chaotic fast. And because we also build ADUs and garage conversions across Stanton, we understand how a bathroom remodel sometimes ties into a JADU or laundry relocation in the same project.
Nate Calloway leads our crew, and he’s the one who walks your bathroom before any number goes into writing. No estimator who’s never swung a hammer. No salesperson reading from a brochure. Just someone who’s seen what these Stanton slabs do to old drain lines and can tell you honestly what your job needs.
Our Bathroom Remodeling Services in Stanton
Full Bathroom Remodeling
A full remodel in a Stanton tract home usually means gutting a compact hall bath, correcting framing or subfloor issues, re-plumbing the supply lines, and rebuilding the shower from the hot-mop up. We typically replace galvanized supply lines with PEX or Type L copper and set new fixtures on properly sloped drains. Because so much of Stanton’s stock is single-story stucco on slab, we plan every fixture location around what the original floor plan gives us. Moving a toilet across the room costs real money here, and we tell you that before you fall in love with a layout that fights the plumbing.
Waterproofing and Shower Pan Replacement
The single most common failure we see in Stanton is a shower pan that was never waterproofed correctly in the first place, or one that’s lived well past its useful life. On a slab home, the pan sits directly on concrete, so any leak wicks into the slab and travels. We strip to the studs and floor, inspect for rot and efflorescence, then rebuild with a hot-mopped or fabric-membrane pan and full waterproofing up the wet walls. In a small, humid rear-yard bathroom with limited ventilation, this step is non-negotiable. Stanton’s coastal-influenced basin climate means humidity sticks around even when it’s not hot, and a poorly waterproofed pan in a converted garage bathroom will fail faster than most homeowners expect.
Permit-Driven Electrical and Plumbing Upgrades
Open a wall in a 1950s Stanton bathroom and you’ll often find what we find: original galvanized supply lines that barely flow and a panel that’s already maxed out. When a permit is pulled, the inspector will require corrections the original house never accounted for. That’s not us upselling, that’s the code doing its job. We build these upgrades into our written estimate as allowances, so when the wall opens and the 100-amp panel is already feeding a garage ADU, the subpanel upgrade is already discussed and priced, not sprung on you mid-tile. This is the single biggest reason our Stanton quotes hold while others move.
Garage Conversion and JADU Bathroom Additions
Stanton’s classic ADU job is a 1950s detached garage at the back of a shallow lot converted into a studio or JADU. That bathroom has to be added over an existing slab, which means breaking concrete for new drain lines, routing a sewage lateral to the main line, and often relocating the laundry that used to live in the garage. We plan the bathroom around the slab, not against it. That’s the difference between a clean build and a job that fights its own foundation. If you’re adding a bathroom as part of a garage conversion or attached JADU, we handle the bathroom and the unit in one coordinated project.

Trusted Brands We Service in Stanton
We specify products that hold up in Stanton’s specific conditions. For bathroom ventilation in converted garages with low ceilings, we use Panasonic Whisper series fans that move real air without sounding like a jet. For shower valves, we default to Delta or Moen cartridge systems because parts are available same-day at local supply houses, which keeps a Stanton job from stalling if a trim piece fails. And for cabinetry and vanities, we work with Bertch and similar plywood-box lines that resist the humidity swings this basin throws at small bathrooms every winter. We also build ADUs with Mighty Buildings, Boxabl, Plant Prefab, and Tuff Shed systems, so when a bathroom remodel ties into a garage conversion, we’re already working with the same prefab partners the unit was framed with.
Common Bathroom Remodeling Problems We See in Stanton Homes
- Cast-iron drain legs pitted at the slab joint. Most 1950s tract homes in Stanton still have original cast-iron under the slab. By now, those pipes are 70 years old and often corroded through at the joint. When we demo a shower, we check the stub-out immediately. If it’s failing, the repair is a few hundred dollars while the floor’s open, not a few thousand after we’ve tiled over it.
- 100-amp panels shared with a garage ADU. Stanton has a high density of garage conversions and JADUs. When we add a bathroom to a home that’s already feeding a converted garage, the panel math gets tight. We plan for a subpanel or service upgrade in the estimate so the inspector’s correction doesn’t stop the job.
- Failed waterproofing on slab-set pans. A shower pan set directly on a slab has nowhere for water to go but sideways into the framing. We see the telltale signs: dark staining at the base of the wall, lifting tile, and a musty smell that never really goes away. Proper waterproofing in a Stanton bathroom is not optional.
- Undersized floor framing from original construction. When a 1950s bathroom was built, the floor framing wasn’t designed for a heavy tile bed. Add years of moisture and you get deflection that cracks grout and loosens tile. We check joist spacing and condition before we set anything, and we’ll tell you if the floor needs stiffening.

What moves the number most is what’s behind the walls: if the original galvanized supply lines are still in place, if the cast-iron drain leg has failed at the slab, and whether the panel can handle the load.

FAQs – Bathroom Remodeling in Stanton
Because 1950s tract bathrooms in Stanton hide original cast-iron drain lines, galvanized supply plumbing, and undersized electrical that a permit inspection will force into compliance. A quote that doesn’t account for those unknowns will move the moment the wall comes down. We handle this by writing allowances into your contract for exactly these items, so when we find a corroded drain leg at the slab or a panel that can’t support the new bathroom, the scope and price are already outlined and you approve the work in writing before we proceed. Call (833) 863-7015 and we’ll show you what a realistic Stanton estimate looks like.
Yes, if you’re moving plumbing, replacing drain lines, altering wiring, or changing the footprint, you need a permit. A surface refresh of tile, fixtures, and paint that doesn’t touch the plumbing or electrical can sometimes proceed without one, but as soon as we touch the wet wall or the shower pan, the permit should be pulled. We handle the permit process as part of the job and schedule the inspections. Stanton’s code enforcement is active, and skipping a permit on a bathroom with new plumbing will surface at resale or when you try to add a garage conversion later. We’d rather do it right the first time.
Yes, and most garage conversion bathrooms in Stanton are built over the existing slab. The process requires breaking concrete to run new drain lines to the main sewer lateral, sloping new shower drains correctly, and often adding a sewage ejector pump if the main line sits higher than the new fixtures. We do this work regularly on Stanton’s shallow-lot garages, where the slab is thin and the sewer lateral is old enough to need scoping before we tie in. The key is planning the bathroom location around the slab and the lateral, not picking a spot on a floor plan and hoping it works.
Because most original Stanton tract bathrooms were built with tile set directly over drywall and pans that were never properly sloped or sealed. Add the basin’s humidity and a small rear-yard bathroom with no exterior ventilation, and water finds the only place it can go: into the framing and slab. A proper pan, whether hot-mopped or membrane, plus waterproofing up the wet walls, is what separates a shower that lasts 20 years from one that fails in five. This is not a place to cut cost, and we won’t let you do it.
Often not, especially if the home still has a 100-amp panel and a garage conversion or JADU is already drawing from it. A new bathroom with a dedicated GFCI circuit, ventilation fan, and heated flooring will push the panel past what it was designed for. We check panel capacity during the estimate and, if an upgrade is likely, we price it as a visible line item so you know the full cost before demolition starts. When the permit inspection requires it, you’ll have already budgeted for it.
